Need load suggestion for M1A

[digger658]

I would like to load some plinking ammo for the M1A using Sierra 150gr. bullets and Varget powder in GI brass? Max. range I would be using these for is 200yds.

How much powder would you recommend

42.5grs Varget, LC case, 150gr SMK, WLR/Rem primer for starters. You don't need to push them very hard at all for 200yds.
